LOUIS IR]. MENIDE'LSON, OF CLEVELAND, OHIO.

WATER-HEATER.

Specification of Letters Patent.

Application filed June 4, 191.2. Serial No. 761,622.

To all whom 5'15 may concern:

Be it known that 1, Louis R. Mnnnrinson. a citizen of the United States,and resident of Cleveland, in the county of Cuyahoga and State of Ohio,have invented certain new and useful Improvements in Water- Heaters, ofwhich I hereby declare the following to be a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

The objects of the invention are to pro vide a water heater by means ofwhich hot water can be quickly obtained for domestic purposes or forheating a building and the invention belongs to that class of heaters inwhich a series of hollow sections connecl-- ed by metal tubing providethe circulating means for the water, and are inclosed in a casingwhereby the heat is confined and made to atl'ect the surface of eachsection in turn and thereby the amount of exposed surface is greatlyincreased and quick results are produced.

The present invention provides for checking the upward How of water inthe sections and redistributing the same so as to somewhat retard theflow of water until the greatest amount of efficiency oi the heat ingmedium can be obtained and also pro vides means constantly dividing andredividing the currents of water and spreading them thus divided over agreater amount of surface.

I am aware that sections have been made for this purpose in whichvertical return bands connecting hollow hubs have been used to cause atree uninterrupted circulation from one hub to another and also sectionshave been built in which hollow casings forming an inclosed water spacehave been employed and connected together by central tubes to formspaced sections.

In the latter forms of sections an unim peded annular space encirclesthe sections and the flow of water therethrough is thereforesubstantially unimpeded.

In the present device no annular uni1npeded water channel of any kind isemployed and no vertical return bends are employed through which thewater can flow freely.

The invention comprises a series of sections having spaced hollow hubsand series of upper and lower hollow arms extending iii-om the hubs andarranged in pairs. These hollow arms are termed in tan like shape andare enlarged at the outer ends and have their order ends overlapping andconununi- (rating with each other at their approximated outer edgesonly. In this manner a transverse as well as vertical circulation isprovided and each column of water rising from one hub is divided intotwo portions which join again at the other hub.

The invention is further hereinafter described, illustrated in theaccompanying drawings, and specifically pointed out in the claims.

In the accompanying d -awings Figure 1 is a vertical section of a heatershowing the improved forms of sections, Fig. 2 is a plan view thereoi"the corner being removed, Fig. 3 is a perspective view 01' one sectionand F ig. i is a vertical section showing the construction of thesection.

In these views A A are the sections incloscd in a casing 13 which may bedouble to retain the heat or oi any desired type of construction; 0, care short pipes connecting the sections. Each section is provided withupper and lower hubs D, D and comprises the'tan shaped arms l 1*) whichare broadest at their outer extremities and are formed in two series,the upper series 1*] extending downwardly and outwardly and the lowerseries E extending upwardly and outwardly. The meeting edges of thesections overlap at F F and openings (i G form means 01 connectionbetween the outer edges of each section with two others, thus dividingeach column of water into two parts and causing them to spread over thebroad surtaccs intermediate of the openings bet'ore returning to theupper hub.

(ii-cater heating elliciency and practicability ol action is obtained bythis form of constrimtion since no single body of water can pass at anyone point and the constant subdivision of the streams and spreading themout in the fan like extremities compels an equal distribution of heatthroughout the using streams of water and also quickly transmits theheat thereto.

The subdivision is continuous as the water passes through each sectionand each stream both before and alter subdivision is exposed over thefan like extremities of the arms. The momentary checking oi the Howafter expansion of the current before subdivision through the smalleropenings also give a momentary rest to the water to give it time toabsorb the transmitted heat. flowing action is permitted.

H is a burner for gas or oil and may be of any character desired.

Having described the invention what I claim as new and desire to secureby Letters Patent is 1. A water heater section comprising hollow hubs,upper and lower series of hollow arms extending outwardly from saidhubs, the outer ends of said series 01": arms broadened and overlappingat their edges, each arm of each series communicating with two arms ofthe other series.

2. In a water heater, a heating element, comprising spaced hubs, upperand lower series of hollow arms said arms having their outer extremitieslaterally extended, each arm of the lower series of arms ccmmuni- Nofree eating with the two arms of the upper series of arms at theiredges.

3. In a water heater, a heating element comprising upper and lower tubesspaced apart on a common axis and closed at their approximated ends, aseries of radially and downwardly extended hollow arms communicatingwith the upper hub, a similar series of radially and upwardly extendinghollow arms communicating with the lower hub, said lower armsalternating in position with said upper arms,each lower armcommunicating with two upper arms at its outer extremity.

In testimony whereof, I hereunto set my hand this 1 day of June 1912.
